Abstract
Copper,zinc-superoxide dismutase (Cu,Zn-SOD) activities were determined by the chemiluminescence
method using the cypridina luciferin analog (MCLA) in 22 human brains from fetuses to adults. Cu,Zn-SOD activity
of the cerebral cortex and white matter increased from 15% in fetuses to 50% of adult
levels in neonates. The activity of the white matter was higher than that in the cortex
in the fetal period, but was essentially the same as those of the cortex in the postnatal
period. Cu,Zn-SOD activity in the central nervous system was highest in the spinal
cord and higher in the order pons, medulla oblongata cerebellum, midbrain, thalamus
putamen, pallidum and cerebrum. These low activities may be related to the vulnerability
of cerebral cortex and white matter in premature infants.
